Trent Merrin

That's a really good point I think. I know we've all been talking about the lack of leadership on the field this year but the captaincy suddenly coming up unexpectedly has really highlighted how much we're actually lacking in that area. There really is noone other than Merrin and Ward in the squad you could see captaining the team. It's hardly surprising that we've looked so directionless on the field this year.

It says a lot about Myler's failings that he's not in the frame for the captaincy.

I've said elsewhere but I think Myler's done. His kicking game has been criticised openly most weeks by the coaches (and Agar was a halfback himself). Seeing his stats for missed tackles hasn't improved my view of him either.
Merrin needs to get vocal with the team now and lead from the front, let's not die wondering.

Id stick Mclelland in to be honest, Myler has looked dire for the last month, his kicking game against Wigan was not even championship standard

Rock and a hard place. The real solution is another first grade half back and McLelland as understudy.
However for this year we have experience v exuberance. McLelland isn't ready yet IMO, but he will get stuck in if called upon and he does have a kicking game.
Very, very difficult call to make with so much riding on these decisions now.
I am hoping Merrin at least fires the team up and gets stuck in - if we are to go down at least let's make a fight of it.
